SYRlNGE-PIPE.

SPECIFICATION formingpart of Letters Patent No. 737,795, dated September1, 1903.

Application filed May 18,1903. Serial No. 157,635. (No modelh T0 a/ZZwhom it ntcty concern,.-

Beit known that LVIeToR C.VANT WoUD, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Syringe- Pipes; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and usethe same.

My invention relates to syringe pipes or tips, and has for its object toproduce such pipe-tips whichwill be adapted to throw a circular spray ineither a forwardly or backwardly direction, as desired. To accomplishthis result, I employ the new and novel construction hereinafter fullyand clearly described and illustrated.

In the drawings, Figure 1 is a side or longitudinal view of my improvedconstruction when adapted to throw a forwardly-extending spray. Fig. 2is a longitudinal sectional view of the saine. Fig. 3 is a longitudinalsectional view of my construction when adapted to throw a backwardlyextending spray. Fig. 4 is a perspective view of the parts of the sprayattachment. Fig. 5 is a perspective view of the end of my improved pipe.

In the drawings like letters of reference designate similar parts of myconstruction.

A in the drawings represents a hard-rubbertube of suitable size andshape with either a plain or iiuted exterior surface, said tube havingone end closed Vor sealed and having its other end attached to a syringeby any suitable means, as the rubber tube B. This tube A is providednear its closed end with an annular groove a and outlet holes or portsa' a' in said groove a. O is an attachment, preferably oval-shaped,adapted to tightly fit on said tube in such a manner as to cover thegroove c. and outlet-holes a'c'. This attachment O preferably comprisestwo interlocking portions c c, as shown in Fig. 4; but, ifdesirable,itn1ay be constructed in one piece. c c are each provided withsuitable threads e c', adapted to engage similar threads a2 a2 on thetube A to retain said attachment O in position on said tube and toenable it to be reversed when desirable. Said oval attachment C isprovided at its center with an. an-

lnular groove c2, the sides of said groove being preferably oblique. c3c3 are passages in the attachment connecting the grooves a and c2. Thuswhen liquid is admitted to the tube A from a syringe it passes to theclosed end of said tube and is forced through 'the holes a a' into thegroove a, then through the hole c3 c3 into the obliqu ely extendinggroove c2, from which it is thrown in the form of a spray either in aforwardly or baekwardly extending direction, according to the manner inwhich the attachment C is placed on the tube A, and it is obvious thatthe direction of the spray may be easily regulated, as desired, byreversing the attachment C on said tube A.

Vhat I claim, and desire to secure by Letters Patent, is-

l. In a device of theclass described,the conibination with a tube, of areversible spray attachment detach ably secured to said tube and havinga discharge inclined to the`longitudinal axis of the said attachment,whereby the direction of the spray is controlled by reversing saidattachment, substantially as described.

`2. In a device of the class described,the combination with a tubeclosed at its outer end, and provided with lateral discharge-apertures,of a reversible spray attachment hav-v inga central longitudinalaperture to fit over said tube and provided between its ends with alateral discharge inclined to the longitudiportion and the outer end, ofa reversible IOO vided with a suitable annular groove and outports beingin communication with the groove let-ports in said groove and ineommunieaand outlet-ports in said lcube, said attachment tion with thegroove in said tube, said attaohbeing adapted to be reversed,substantially ment being adapted to be reversed, substanas und for thepurpose described. I5 5 tally as and for the purpose described. Intestimony whereof I afx my signature 5.
